Calibration Traceability
Apogee Instruments SP-500 series pyranometers are calibrated through side-by-side comparison to the mean of
four transfer standard pyranometers (shortwave radiation reference) under high intensity discharge metal halide
lamps. The transfer standard pyranometers are calibrated through side-by-side comparison to the mean of at least
two ISO-classified reference pyranometers under sunlight (clear sky conditions) in Logan, Utah. Each of four ISO-
classified reference pyranometers are recalibrated on an alternating year schedule (two instruments each year) at
the National Renewable Energy Laboratory (NREL) in Golden, Colorado. NREL reference standards are calibrated to
the World Radiometric Reference (WRR) in Davos, Switzerland.
